How to Inspect an MSI Surface Delivery Before You Accept It

I'm a quality compliance manager for a stone and tile company. Every year, I review a few hundred incoming and outgoing deliveries. The one thing I can tell you: the minute the driver leaves, the argument changes. Accepting a damaged delivery is not the same as rejecting it. This checklist is for the moment before you sign—when you still have leverage.

Use it if you're a builder, designer, or store owner taking delivery of MSI quartz, granite, marble, slate tile, engineered flooring, or decorative stone. It's also useful for showroom staff opening a resupply order.

(Should mention: if your search is MSI MAG B650 Tomahawk WiFi price Germany or MSI Pro MP251 E2 specs, this is the wrong MSI. We're MSI International Surfaces, not the computer hardware company. I don't know motherboard or monitor prices. I'd rather be honest about that than invent specs.)

Step 1: Confirm the item before the truck opens

Check the packing slip against your purchase order. Don't rely on the product name alone. Look for the item code, color name, and batch or lot number.

Stone and tile are natural materials. Slabs from one block can look different from slabs in another block. If you need consistency across a large project, ask for the lot number to be printed on the delivery receipt. In my experience, a missing lot number is the first sign that the order might get complicated.

Step 2: Measure dimensions and thickness

Check dimensions before you accept. Slab thickness matters for fabrication—2cm and 3cm quartz are not interchangeable in every application. Tile thickness matters too: a 12x24 tile in 8mm vs 10mm affects the floor build-up and transition strips.

Don't assume the label is correct. I remember one delivery where the slip said 3cm but the slab measured 2.8cm. That's out of tolerance for most fabrication shops. We caught it because someone actually took a caliper to it.

If you're using metal edge profiles, thickness is a dealbreaker. Schluter trim, for example, is sized to the tile thickness. If the trim is for an 8mm tile but the tile is 10mm, it won't sit flush. I want to say 1/4 inch is the most common profile for 8mm tile, but don't quote me on that—check the exact spec.

Step 3: Inspect in daylight, not under warehouse lighting

Move the slab or tile to a well-lit area. Fluorescent lights make almost everything look okay and hide surface defects.

Look for:

• Chips, cracks, or hairline fractures
• Uneven polish or grinding marks
• Pinholes in engineered quartz
• Blotchy resin or dull spots
• Veining that doesn't match the approved sample

Natural stone will have variation. That's not a defect. But there's a difference between variation and a crack that will split when we cut it. If in doubt, mark it on the delivery receipt and take photos.

Step 4: Check edges and profiles against the sample

Edges are easy to overlook. You ordered a eased square edge, but the delivery shows a full bullnose. That's a reorder, not a minor fix.

For tile, check the edge trim too. If the order includes Schluter trim, verify the material and profile match the spec—anodized aluminum vs stainless steel, radius vs square. It might sound picky, but once the trim is set in mortar, changing it means cutting tiles out.

Step 5: Examine the color in real conditions

Samples under a showroom light look different from a kitchen with south-facing windows. If you can, put a sample next to the delivered slab in daylight and under LED lights.

There's a technical side to this. In color measurement, the difference between two colors is called Delta E. According to Pantone's color matching system, a Delta E under 2 usually looks consistent to most people. Above 4 is noticeable. But you don't need a spectrophotometer for a simple check—just look at the slab next to the sample.

Even after approving a delivery, I've second-guessed. What if the color is too dark? I didn't relax until after installation. Set that worry aside: if the material isn't what you approved, don't sign. The cost of fixing a countertop is larger than the cost of refusing a slab.

Step 6: Verify paperwork and care instructions

Before you sign, check that you got:

• The invoice and packing slip
• A care and maintenance sheet
• Warranty information
• Lot numbers and item codes

If a supplier says these slabs are maintenance-free, that's a red flag. Under FTC advertising guidelines, claims need to be substantiated. And practically, almost every natural stone or engineered surface will need some cleaning and occasional sealing. A supplier who overpromises is one you should question.

If you're emailing a claim, use the Snipping Tool. The shortcut is Windows + Shift + S. Since that's the question behind many how to take screenshot on Windows 11 searches, I'll save you the click: Windows + Shift + S, then paste into your email.

Step 7: Make the decision now, not later

Signing a delivery receipt is not the end of the conversation. It's a paper trail that works against you if you discover a problem after the driver leaves.

In my opinion, the phrase they'll fix it later is how small problems become chargebacks. Looking back, I should have rejected a batch of tile where the shade didn't match the approved sample. At the time, the rep said it would blend during installation. It didn't. The tiles had to be replaced after the bathroom was already set.

If the order has a real issue, write it on the receipt, photograph the material, and let the driver know. That's not being difficult—it's being clear.

When this checklist doesn't apply

This is for stone, tile, and engineered flooring. If you're inspecting something like forged carbon fiber panels or other composites, the failure modes are different—resin voids, fiber weave consistency, and delamination. Don't use my stone/tile list for that process.

And one more thing: pricing changes. This checklist was accurate as of early 2025. Material availability and stock vary by region, so verify current inventory and lead times with your MSI rep before budgeting.

Take the extra ten minutes. The driver might be in a hurry, but a rejected order costs time, freight, and fabrication hours. A signed receipt for the wrong material costs more.
